A nun who uses a wheelchair touches a common-or-garden stone in a park and is cured. In the archbishop’s eyes, the stone is far too secular an object for the Vatican to recognise the event as a miracle. The nun’s Mother Superior uses a bluff to save the day, convincing the archbishop to pass the matter to higher echelon by telling him that Saint Andrzej Bobola appeared to her and affirmed the stone’s divine origins. As bad luck would have it, the Chief Rabbi of Poland, who uses crutches, sits down on the same stone. He, too, is miraculously cured. The priests are left in no doubt. They either have a shared miracle or no miracle at all.
